Littell Machine Company, Chicago, 111., a corporation of Illinois 1 Application March 10, 1950, Serial No. 148,893

c The invention relates to loading cars and has reference in particular to a loading car of improved design for use in transporting and elevating coils of metal stock whereby to facilitate the loading of said coils onto centering reels such as disclosed in the copending application of Littell and Skriba Serial No. 737,366, filed March 26, 1947, and entitled Hydraulic Reel.

A plurality of horizontally supported arms in associated relation with a spindle are provided.

by the centerin reel as herein mentioned and said arms have movement in a radial direction so that a coilof metal stock may be securely gripped by the expanding movementfof the arms or released when said arms are moved in a contact ing direction. The coil of metal stock upon being supported by the arms is rotatably mounted for feeding the metal strip of the coil to punch presses or similar processin machines and it is not unusual for such coils to weigh many tons, all of which requires a large centering reel of rugged construction in addition to complicating the task of installing the coil in proper position on the reel.

For such installations, which operation is gen- 7 erally referred to as "loading the reel,the invention provides 'an improved loading ,car of special construction having car wheels for travel on a track provided for the purpose. Said tracks may extend from an unloading platform to the centering reel and in order to additionally facilitate the loading of the reel the coil supporting table of the car is mounted for movement in a vertical direction. This ability to move the table vertically renders it possible for the coil to be accurately aligned with the horizontal arms whereby both operations, that of transporting the coil from the loading platform and properly locating the coil on the reel, can be performed by the loading car, thus speeding up the operations since intermediate handling of the coil is eliminated. l

Accordingly an object of the invention is to provide a loading car of sturdy construction having a vertically movable table equipped with means for stabilizing the said movement to prevent tilting or dipping thereof during the loadin operation.

A more specific object of the invention is to provide a loading car of the character described wherein the stabilizing means'for the vertically movable table consists of linkage connecting with each end of the table and geared together so as to require movement of each end of the l able simultaneouslyaud to a e e t t.-

11 Claims. (Cl. 254-2) A further object is to provide hydraulic means of novel and improved construction for elevating the movable table of the present loading car.

A further object resides in by the side frames of the car and which incorporates stabilizing linkage for mainatining the table absolutely horizontal during said vertical 7 movements.

Another object is to provide driving means for a loading car as described which will have a geared connection car for moving the car along tracks provided for the purpose. i

With these and various other objects in view, the invention may consist of certain novel features of construction and operation as willbe more fully described and particularly pointed out in the specification, drawings and claims appended hereto.

In the drawings which illustrate an embodiment of the invention, and wherein like reference characters are used to designate like parts- Figure l is a top plan view of the loading car of the invention with parts in section to better illustrate certain structural features of the same;

Figure 4 is a vertical sectional view similar to Figure 3 but showing the table in elevated position;

Figure 5 is a fragmentary vertical sectional view taken substantially along line 55 of Figure 1 and showing in detail certain structural features of the hydraulic cylinder for elevating the table; and

Figure 6 is a fragmentary vertical sectional view taken substantially along line 6- -6 of Figure 1. V

The loading car selected for illustrating the invention includes a pair of frame members located on each side of the car and which members journal the car wheels and support the of the car is indicated by numeral I 2. Referring more particularly to the frame members,

the provision of a loading car having a vertically movable table which is elevated by hydraulic means, which is guided in its movement by guide blocks carried with all four wheels of the V which are also shown in Figures 1 and 6, each said member is formed by a pair of side walls l3 and I l, the side wall [4 being disposed inwardly of the car, whereas wall I3 is located on the outside of the car as regards each frame 5 member. The side walls are connected by a top wall l5 and by a bottom wall l6. The side walls l3 and'Mbfrzachrframe membenare-cone. tinuous from end to end-of the caryas will be clear by reference to Figure 1. However, the top wall is interrupted centrally thereof since each-*- frame member supports a cylinder support-blocks. l7 constituting part of the hydraulic cylinder to be presently described in detail."

The table of the present loading car, as best shown in Figures 2, 3 and 4, essentially consists of a top wall 40 which is provided with a depressed portion centrally of the top wall, the same .extendinggin' a longitudinal directionof the car; This depressed portion is for the purpose of receiving and locating the coil of metal stock and asia result of the same the coil is supported in a mannerflto prevent either forward or rearward rolli'n'g' ofthe coil off of the car.

In accordance.withI-therinvention the table it is movable upianddown inwvertical directions for elevatingv the coil.ofrmetal-stocksupported there by .Fig-ureS shows the table in-down position, in which lposition-hthemable' rests. on 1 blocks to be presently; described 'provided for the purpose by the. respective frame -members, and Figure 4, shows the,tableninuelevated position with the stabilizing .linkage.lextendedaand "operative to means althoughwotherc instrumentalitiessuch as v a rack .and .pinionlcouldvotcourse be employed. Eachframe membrsupportsanhydraulic cylin der. indicated by numeral 56, Figure 5 the cylindiet containing a piston 51'and a piston'rod 53 Which extends. throughlthe. cylinder cap member 59; .Each cylinder 56 also has: secured thereto at its upper end. .a cylinder ringifiilgth same-having located diametrically. of .thewringa Bil and which trunnions are adapted to rest'in semi-circular recesses provided therefor. in..-.thecylinder sup- In this manner. thecylinders are Leach. supported .Iby ,their .respective frame member in a manner. permitting swinging movement of. the cylindenwith respectto-a transverse axis. since the trunnions 6 I of each cylinder are .disposed in a transversefl direction and-in submay leak past piston 51 stantial alignment with each other. The cap bars 52 hold the trunnions 6| in journalling relation on the cylinder ring l1. A fluid medium is admitted to cylinder 56 at the lower end thereof through the inlet pipe 53 and the action of this fluid medium, which is at a high pressure, is to elevate the pistons 51 and to accordingly elevate the table 4llv having connection to the pistons through the piston rod 58 and connecting blocks 64. A block 641s located under each edge portion 4| and 42 and is suitably welded thereto. Also each block is confined between transverse plates 55 and 66 which extend from their respective guide plates, either 53 or 54, to the adjacent side wall. This structure is shown'in Figure 5 and is additionally disclosed in Figures 1 and 3. The blocks 64 provide means for bolting or otherwise securing the top wall to pistons 58 of the hydraulic cylinders and as shown in Figure 5 a socket screw 61 is employed for uniting the block 64 and thus the table 40 to piston 58 of the hydraulic cylinder. The structure of Figure 5 is of course repeated at both sides of the loading car.

During use of the loading car and as a result of a number of elevating operations by the hydraulic cylinders a quantity of hydraulic medium in each cylinder, which must beremoved so as not to interfere with the full stroke of the piston. The cylinder wall at its extreme upper end is provided with an opening which communicates with an exhaust pipe 58. The exhaust pipe 68 operates continuously to exhaust the space in back of pistons 51 and accordingly said pistons are at all times able to complete a full stroke in an up direction.

The guide plates, namely, 53 and 54, previously identified, help to guide the table In in its vertical movements. The guide plates are fixed to and accordingly move with the table and said guide plates, as best shown in Figures 1 and 5, have suitably fixed thereto a guide block identified by numeral 10. The guide block extends vertically of its respective guide plate substantially centrally thereof, as shown in Figure 4, and the block has interfitting relation with its adjacent cylinder ring [1, each ring for the purpose being provided with a guidebushing H. Each cylinder ring l1, as previously described, is fixedly secured to a frame member and accordingly the ring comprises a fixed part of the frame of the car. The guiding action of the guide blocks with respect to the cylinder ring limits the end sway of the table as it moves vertically and as a result of the journalling trunnions 6| on the cylinders binding stresses between the hydraulic elevating structure on the one hand and the guiding structure on the other is entirely eliminated. This is the principal reason for journalling the hydraulic cylinders by the trunnions 5|, since otherwise a binding action could take place involving either the guide blocks or their adjacent hydraulic cylinders. If there should be any error in vertical alignment between thetwo it is compensated for by pivoting J movement of the hydraulic cylinders on their respective trunnions.

An important improvement as regards the present loading car. resides in the provision of stabilizing means to prevent tilting or tipping of the table during movement of the same in an up and down direction. It will be understood that the coil will most often be located off center and if it were not for the stabilizing means the table might otherwise tilt to an extent which would prevent elevating movement being im- 6 parted thereto. However, with the stabilizing means both ends of the table must move simultaneously and to a like extent so that the stresses and strains which would otherwise be applied to the cylinders and to the guide plates .are completely eliminated. The stabilizing structure includes a pair of journalling shafts 12 and 13 which extend transversely of the loading car on the respective sides of the transverse center and between the cylinders and the car wheels at its end of the car. Each journalling shaft has reduced end portions 14 which extend through the side walls l3 and 14 of the frame members, being journalled by the. frame members, since bearing sleeves 15 are provided in each frame member for the purpose. Each journalling shaft is threaded at each end thereof and as shown in Figure 6 it will be seen that this threaded end projects beyond bearing sleeve 15 to receive a securing nut 16. Eachjournalling shaft is accordingly locked against rotation. The central portion of each journalling shaft rotatably supports a sleeve identified by numeral 11 for shaft 12 and by numeral 18 for shaft 13. Each sleeve at its respective endsis provided with a bearing 19 anda washer 85 is located at each end of the sleeve, being interposed between the sleeve end andthe adjacent bearingsleeve 15. The sleeves 11 and 18 are accordingly mountedfor free rotation on their respective shafts and said sleeves are adapted t rotate in unison since they are geared together by means of the gear segments 8| and 82. to sleeve 11 substantially centrally of the sleeve, whereas, gear segment 82 is welded in a similar manner substantially centrally of its sleeve 18. The segments have meshing relation so that the v sleeves are required to rotate simultaneously and to a like extent.

A plurality of stabilizing arms are actuated by the up and down movement of the table and in accordance with the invention a pair of said arms is provided by each of the sleeves 1-1 and 18. Arms 83 and 84 are welded to the sleeve 11 at the respective ends of the sleeve and arms and 86 are welded in a similar manner to arm 18 on each side of gearsegment 82.. Arms 53 and 85 on one side of the loading car are disposed in substantial alignment with the reinforcing plates 45 suitably secured to and depending from the top wall 45 of the table on the frame member I! side of the car. The arms 84 and 86 are disposed in substantial alignment with the reinforcing plates 46 similar to 45, which, however, are located on the side of the loading car adjacent frame member l2. An operative connection is effected between the stabilizing arms and the table by means of links 81, 88, 95 and 9!. The links 81 connect arm83 to the reinforcing plate 45, the pin 92"connecting the links to the arm and the pin 93 connecting the links to the plate, all as best shown in Figure 2'. The arm 84 is joined to the table by the links 83 which connect the arm to a plate 46, the pins 92 and 93 being employed as described. The arm 85 is connected by the .links which pivotally join with the table since they have connection with a plate 45 and finally the arm 86 is joined by the links 9| which connect at'their upper end with a plate 46. As regards each arm, similar pins a2 and 93 are employed.

For operating the present loading car the motor 24 is suitably energized to power the drive shafts 25 and 34 which effect movement of the loading car along the tracks provided therefor.
